Subject: [PATCH v2] [media] Delete unnecessary variable initialisations in
seven functions
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 22 Feb 2018 21:45:47 +0100
Some local variables will be set to an appropriate value before usage.
Thus omit explicit initialisations at the beginning of these functions.
Signed-off-by: Markus Elfring <elfring@...rs.sourceforge.net>

v2:
Hans Verkuil insisted on patch squashing. Thus some changes
were recombined based on source files from Linux next-20180216.
